Riley, 24, is set to clock up his 150th Wolves appearance, more than seven years after he made his debut as a teenager in 2005.
He has scored more than 100 tries for the club, including 29 in a prolific 2010 season.
The former Woolston Rovers amateur came through the Wolves academy, and also spent a handful of games on loan at Harlequins in 2011.
Meanwhile, Wood is set to make his 300th appearance for the club.
Head Coach Tony Smith told the club’s official website: “Congratulations to the players. Each player puts a different worth on their personal milestones; the old adage goes ‘all players would substitute that for a good performance and good team performance’.
“The good thing is we’ve got players who are staying and wanting to stay at this club racking up some milestones. They are at a club that they love which is important and they are playing like that as well.”
Smith recently dismissed speculation linking with Wood to a move away from the club, after the Wigan-born forward spent the opening round of the season on a dual-registration assignment with Swinton.
Wood, 31, made his debut back in September 2000, and has been a mainstay of the first team ever since, only failing to make more than 20 appearances in a season in an injury hit 2008 campaign.
